Defect states in compressible active polar fluids with turnover
Ludovic Dumoulin, Carles Blanch-Mercader, Karsten Kruse
Biological active matter like the cytoskeleton or tissues are characterized by their ability to transform chemical energy into mechanical stress. In addition, it often exhibits ori…
The importance of being discrete -- An agent-based model for active nematics and more
Mathieu Dedenon, Carles Blanch-Mercader, Karsten Kruse +1
We propose an agent-based model of active flexible rods. Inspired by cytoskeletal flows, we introduce activity by an internal flow that contributes to the dissipative forces. The a…
Effective viscosity of a two dimensional passive suspension in a liquid crystal solvent
S. Dang, C. Blanch-Mercader, L. Berlyand
Suspension of particles in a fluid solvent are ubiquitous in nature, for example, water mixed with sugar or bacteria self-propelling through mucus. Particles create local flow pert…
Src Kinase Slows Collective Rotation of Confined Epithelial Cell Monolayers
Nastassia Pricoupenko, Flavia Marsigliesi, Philippe Marcq +2
Collective cell migration is key during development, wound healing and metastasis and relies on coordinated cell behaviors at the group level. Src kinase is a key signalling protei…
Emergence of bidirectional cell laning from collective contact guidance
Mathilde Lacroix, Bart Smeets, Carlès Blanch-Mercader +5
Directed collective cell migration is central in morphogenesis, wound healing and cancer progression1,2. Although it is well-accepted that the molecular anisotropy of the micro-env…
Passive defect driven morphogenesis in nematic membranes
D. J. G. Pearce, C. Thibault, Q. Chaboche +1
Topological defects are ubiquitous on surfaces with orientational order fields. Here, we study equilibrium states generated by the feedback between geometry and nematic order on fl…
Density-polarity coupling in confined active polar films: asters, spirals, and biphasic orientational phases
Mathieu Dedenon, Claire A. Dessalles, Pau Guillamat +3
Topological defects in active polar fluids can organise spontaneous flows and influence macroscopic density patterns. Both of them play, for example, an important role during anima…
Integer topological defects of cell monolayers -- mechanics and flows
Carles Blanch-Mercader, Pau Guillamat, Aurélien Roux +1
Monolayers of anisotropic cells exhibit long-ranged orientational order and topological defects. During the development of organisms, orientational order often influences morphogen…
Quantifying material properties of cell monolayers by analyzing integer topological defects
Carles Blanch-Mercader, Pau Guillamat, Aurélien Roux +1
In developing organisms, internal cellular processes generate mechanical stresses at the tissue scale. The resulting deformations depend on the material properties of the tissue, w…
Collective stresses drive competition between monolayers of normal and Ras-transformed cells
Sarah Moitrier, Carles Blanch-Mercader, Simon Garcia +6
We study the competition for space between two cell lines that differ only in the expression of the Ras oncogene. The two cell populations are initially separated and set to migrat…
